Cold light mirrors are designed to let infrared radiation pass through, so that the accompanying heat radiation and heat load can escape and overheating of the technical applications is avoided.
The use of heat protection filters in technical components guarantees a reduction of heat stress through high reflection in the infrared spectral range. The blocking of infrared radiation with simultaneous high transmission in the visible range enables, the transmission of visible radiation without increased temperature stress in the application.
The reflector helps in allowing infrared radiation to pass through. This is achieved by reflecting visible light. Lesser infrared radiation means less heating of the illuminated objects in the light beam
